Catholics do enforce their ideas on the rest of the world, as many Christians in positions of power do. Especially in the US. Especially recently, with the surge of extremist anti-LGBT and anti abortion laws, all predicated philosophically on Christian doctrine. People who find homosexuality unnatural and wrong should not be respected, or simply let be, any more than virulent racists or anti-Semites. Tolerance for the intolerant only leads in the extermination of the tolerant.
